通过盐酸刻蚀、氨水浸泡和疏水长链接枝,成功构建得到接触角达154°、滚动角为6°的超疏水镁合金表面。利用接触角测试、扫描电镜观察、红外光谱分析、防黏附和电化学实验等分别对超疏水镁合金表面的润湿性能、表面微结构与化学组成、防黏附行为以及耐腐蚀性能进行了考察。结果表明:盐酸刻蚀和氨水浸泡使得镁合金表面产生了微-纳复合结构,而硬脂酸修饰使疏水烃基长链通过化学键接枝到具有微-纳复合结构的镁合金表面。正是由于其特殊的表面微结构和化学组成,使得超疏水镁合金表现出良好的防黏附和耐腐蚀性能。 |

A superhydrophobic magnesium alloy surface with a contact angle of 154° and a sliding angle of 6° was successfully prepared by hydrochloric acid etching, ammonia immersing, and long hydrophobic chains grafting. The surface wettability, microstructure and chemical composition, anti-adhesion behavior, and corrosion resistance were investigated by means of contact angle measurement, SEM observation, FT-IR analysis, anti-adhesion and electrochemical experiments respectively. Results show that the micro- and nano-scale multiple structure presents at the magnesium alloy surface after hydrochloric acid etching and ammonia immersing, while the long hydrophobic alkyl chains are grafted onto the micro- and nano-scale surface with chemical bonds upon stearic acid modification. Just based on the peculiar surface microstructure and chemical composition, the resulting superhydrophobic magnesium alloy surface possesses the excellent anti-adhesion behavior and corrosion resistance. |
